I'd like to have a couple of complete sets of paper money and coins .   Yeah . You can take them home and either use them as a gift or keep them as mementoes .   Ah , where can I find old paper money and coins used before and after 1949 ?   I'd suggest that you go to the Philately Store in Nanjing Road East , where the items are authentic and the prices are reasonable .   Good . Sorry to have troubled you so much , Miss .   You're always welcome . Anything else can I do for you , sir ?   No , thanks . I did not notice it has been dark outside . I think it is time to dinner .   I guess it is . The restaurant is on the second floor . Please enjoy your dinner , sir !
